This set indeed will not have a colour wheel this immediately tells me you are not electronically trained , my advice seek a pro to look at your set . There could be a number of faults such as 1/ faulty Lcd Backlight, 2/ faulty inversion circuit ( the back light is similar to a neon and requires a starter and high power inverters )
3/ Faulty Tcon board
4/ it could also be the printed copper ribbons that interconnect the boards in the set these get hard brittle and crack over time .
5/ you could actually have a faulty lcd screen .
No to save you money and further damage to set seek an engineer , sorry to sound condescending but I don't think DIY is going to solve this problem.

LCD tv don't have colors wheel,only DLP tv have colors wheel.Distorted picture have only two symtoms.The Tuner signal board is dead,replaced that.Same problems than Ur LCD screen is dead,not worth repairing if the LCD screen is the problem.Because the LCD can only buy at the tv dealer they sell them very expensive cost about the same as a new tv.Tries Shopjimmy.com,Ebay.com for the Tuner board.

Based on the Model# provided, your TV does not have a color wheel. Could be one of the PCBs is bad, or even the panel. Have a TV technician look at it.

Good luck

Why is my tv blurry and distorted? We have reset all settings. Still blurry.


It looks like a light shining on the screen when you were recording the problem.Also, you are taking the picture from a bad angle for lcd types of tvs.Try a new recording,also get the tv on an HD channel for a better,clearer picture.Many hd tvs look bad on non HD channels.

Hello

Make sure TV is on the correct channel or input. Check the cables for correct routing from TV to any other devices. Check cables to ensure they are tight and secure.

An analog signal converted to high defintion resolution will cause lines, blurriness or fuzziness in the picture. Change the resolution to a lower or native setting using the media device (cable box, DVD,). This may be an issue that requires a service call to cable provider.

A problem on one channel may just be a error on that channel. If using an antenna, it might need to be adjusted in order to ensure good signal strength. For digtal channels, go into TV Menu. Check the DTV signal. Weak signal can cause picture distortion.

If another device is being used such as a cable box, DVD player or VCR switch between devices and test picture. Check routing of cables that are used to control the image. This should be a series of red, white and yellow cables.

If a VCR with a cable box, make sure the VCR and TV are set to the correct channels for video signal to pass through. If problem is still occuring, try another set of cables. bad cables can cause picture distortion.

Bad cables can cause picture distortion as well. Try another set of cables. If picture is better than when using the cables replaced, this was the issue. If cables are not an issue TV may require service.

Volume is fine but picture is to blurry to see Menus, and wont change channel without remote. do not have remote


need the model of the tv. but with a blurry picture on a projection tv its means that your color board or color wheel is going bad. but more likely and much cheaper would be a bad bulb or ballast for the bulb. that will be your solution. hope i helped let me know.

most of the time when tv starts to blurr or colors r off, then the bulbs are usually going bad. i would try to locate a local repair and purchase new bulbs. they can get exspensive. they are also different colors. you can adjust the angle of the bulbs.

Dark colors Picture going out


It is hooked up to Direct TV. When I change the channel on the TV to another input it looks fine but without a picture. as you do not see tint in another channel means your color section is ok it is due to video or luminance section.

Distorted sound on all right channel inputs


yep but if your not a tech you should take this easy repair to a pro. Your problem is an open emitter resitor and happens when the units over driven or a speaker is bad for a while while it was working. if your a tech then check all of the emmitter resistors. also it could be a bad output device. Good Luck
